The diagram above shows two similar polygons. Write a rule for finding the coordinates of a point on figure B from the corresponding point on figure A.

• The rule used is ​(x,y)→​(1.5​x,1.5​y) to the vertices of a polygon to get a new polygon.

• The rule used is ​(x,y)→​(2.5​x, 1.5​y) to the vertices of a polygon to get a new polygon.

• The rule used is ​(x,y)→​(1.5​x, 2.5​y) to the vertices of a polygon to get a new polygon.

• The rule used is ​(x,y)→​(2.5​x, 2.5​y) to the vertices of a polygon to get a new polygon.
